DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0016] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0017] Referring to FIGS. 4 to 8, there is shown a method of manufacturing shoes insole, wherein the method employs a high density thermoplastic material 51 and a low density thermoplastic material 52 which are respectively fed into the silo A 61 and silo B 62 of a pressing device 60. These materials are then transported into a heated mold 63 such that the melted materials 51,52 are rolled and pressed by the rolling device 70 to form into a single layered long and flat dual density rubber board structure.

[0018] In accordance with the present invention, in the course of rolling and pressing, after the two materials 51, 52 are pressed by rollers 71 of the rolling device 70, the top and bottom surface of a foamed woven 53 and a non-woven cloth 54 are pressed and fused together to form a complex rubber board 55, a tailoring device cuts the complex rubber board 55 to form a shoes insole blank 56, and the blank 56 is then undergone a thermal pressing process to form a shoes insole 57 in accordance with the present invention.

[0019] Referring to FIG. 9, there is shown a second preferred embodiment in accordance with the present invention. When the high density thermoplastic material 51 and the low density thermoplastic material 52 are rolled and pressed, the top and bottom of the two layers of the nonwoven cloth 54 are fused into a layer of dual density rubber board 55A.

[0020] Referring to FIG. 10, there is shown a third preferred embodiment in accordance with the present invention. When the high density thermoplastic material 51 and the low density thermoplastic material 52 are rolled and pressed, the nonwoven cloth 54 is also transported and rolled, such that the top of the nonwowen cloth 54 is thermally fused with a layer of dual density rubber board and thus a layer of dual density rubber board 55B is formed in accordance with the present invention.

[0021] Referring to FIG. 11, there is shown a fourth preferred embodiment in accordance with the present invention. When a single density thermoplastic material 81 is transported into a heated mold 63 using a pressing device 60, the melted or fused single density thermoplastic material 81 is rolled and pressed into a long and flat rubber board structure, wherein the single density thermoplastic material 81 is transported to a heated mold 63 so that the melted thermoplastic material 81 is pressed by the rollers 71 of the rolling device 70 to form long and flat rubber board structure and the foamed woven cloth 53 and the non-woven cloth 54 are fused to form into a layer of single density complex rubber board 82, and a tailoring device cuts the complex rubber board 82 into a plurality of shoes insole blank 83, and the blank 83 is thermo pressed to form shoes insole 84.

[0022] Referring to FIG. 12, there is shown a fifth preferred embodiment in accordance with the present invention. When the single density thermoplastic material 81 is transported to a mold 63 using a pressing device 60 to the rollers 71 of a rolling device 70, the top and bottom layer are at the same time transport the nonwoven cloth 54 for rolling, such that the nonwoven cloth 54 is thermally adhered a layer of rubber board and formed into a single density complex rubber board 82A.
